Hello all,
 

Developer for over 10 years but only lately I've started to fiddle with L2 client files, I'm a complete noob at this.


Are there any resources I can have to learn how to decompile and re-compile the files that ship with the game?

I have a ton of compilers and decrypters but can't make sense of how to use them and for what scenarios.

 

Understanding the files' structure an what they are doing would be a great start.

If you have any links/documents to share would be great!

 

Thanks in advance

Which files were you looking to decompile exactly?

I first would like to understand how things are tied together so I can later on modify the UI to help me gain more info from the game.

A simple example (simple in my mind at least) of what I'd like to do is to display buffs canceled/removed for a brief period of time, or to have some kind of indicator of how much time is left of zealot a GK or Titan has. Things like that which I believe require an overall understanding of how the files work and what and where should be modified.

So far I've managed to:

- Update Interface.xdat (XdatEditor)
- Find out that for Interface.u you need a decompiler and a decrypter/encrypter (WOTgrealExporter)
For this one, I get an error when I try to extract the.uc files

- Make use of UnrealEngine2Runtime  to check some classes, but that's all I managed to do with it, I don't really understand its overall use

- L2 File Editor EN by Miko v2 - I managed to open some files but for some of that same type it did not work (Skillgrp.dat)

 

That's where I am so far. Bits and pieces that I managed somehow to tie together but I still don't see the full picture.

      Need OOG bot that works with L2J Interlude

      By Alex K. · Posted

      Both are in-game bots. I'm looking for an out-of-game bot ((one that doesn’t require the L2 client).     Hmm, never heard about this bot. Will check, thank you

      🎉 L2Mid is back! After a 3-year pause, we’re launching a new Interlude server based on the original Interlude client (old school 😉).   What to expect • The classic Interlude spirit • Old friends, rival clans, and returning legends • A season focused on pure nostalgia   This may be our final Interlude server. (maybe 😉) 🗓️ Opening: December 5, 2025 at 20:00 (GMT+2)   https://l2mid.com

      Regarding the issue of importing UKX files into Unreal Engin

      I imported this file using Unreal Engine 2 Runtime, modified it, saved it back, and then placed it on the client.
